Abstract. Modern wideband radar systems makes possible to obtain high resolution inverse synthetic aperture radar images of objects. One of the difficult actual approaches in radar test facilities is wide angle autofocusing processing. This paper proposed a recommendations to wide angle (above 10 degrees) inverse synthetic image autofocusing processing based on dividing a large angle sector into several small sections. Also proposed an experimental results of autofocusing processing in 30 and 60 angle sector.

Key words: inverse synthetic aperture, radar images, radar cross section, autofocus processing.
